Introduction

In the PET bottle blowing process, the heating stage dictates the entire line’s speed and quality. We built the medium-wave carbon fiber heat lamp specifically for this job. It replaces older halogen and short-wave designs with a focused, fast-response heat source that gives you tighter control over parison temperature without overloading the machine’s electrical budget.

Technical Deep-Dive: Power, Voltage, and Dimensions

Medium-wave carbon fiber lamps are designed to deliver high heat density in a compact footprint, and the numbers tell the story. We spec these lamps to run at 400V, which allows the same power output with lower current compared to a 230V unit. Lower current means thinner wiring, smaller contactors, and less heat buildup in the control cabinet. Wattage is typically 2500W in a 300mm length. This combination concentrates energy into the parison zone, giving you rapid heating and fast recovery after bottle indexing. The 300mm length matches standard blowing head spacing, so you can drop the lamp into existing mounts without redesigning the clamp or oven section. The trade-off is straightforward: high power density demands proper cooling. If your machine runs at high duty cycles, the reflector area and lamp mount must be designed to shed heat, or you risk thermal stress on nearby components.
